Powers: X Gene ManipulationNeil Potter has the ability to manipulate the X Gene. This allows him to control mutants in a variety of way, he is able to grant people the X Gene. With physical contact with others he can grant them abilities by placing an X Gene within them, and is capable of suppressing and removing the X Gene from other mutants. He is able to control those whom he has given abilities and see through there eyes and has been able to control several people at once, enough to lead an attack on Washington D.C. He is able to manipulate them via forcing them to use their abilities in a certain way, or to control them via puppet like control. He is able to control the abilities of other mutants whom he didn't grant abilities too, but cannot command them in a puppet like manner. He is capable of tampering with Mr. Sinister's X Gene to temporarily grant himself other abilities, but he cannot grant himself immensely powerful abilities such as control over matter or time.
